“…The material was collected from 75 patients of the Regional Hospital in Zielona Góra. It gives 10 images per case which was the recommended amount by the specialists from the hospital [5,9] and allows for a correct diagnosis by a pathologist. The set contains 25 benign, 25 malignant and 25 fibroadenoma cases.…”

“…In literature, there have been many different approaches presented to extract cells from microscope images [10,11,12,5,6,7,9,13]. This task is usually done automatically, using one of the well known methods of image segmentation [14,15].…”
Fibroadenoma is a benign tumor that has some features similar to a malignant one. The aim of this study was to examine the impact of fibroadenoma cases on the results of the automatic breast cancer diagnostic system based on the quantitative morphometric analysis of fine needle biopsy microscopic images. The database of 50 patients (500 images) of benign and malignant lesions used previously in our research was enriched by an additional 25 patients (250 images) of fibroadenoma cases. Experiments were performed using the k-means based hybrid segmentation method. The system was tested on a set of real case medical images with promising results.

“…What we have on input is cytological material obtained using the Fine Needle Biopsy (FNB) technique and imagined with a Sony CCD Iris camera mounted on top of an Axiophot microscope. The material comes from female patients of the Onkomed medical center in Zielona Góra (Marciniak et al, 2005). The image itself is coded using the RGB colorspace and is not subject to any kind of lossy compression (a raw color bitmap format).…”
This paper describes three cytological image segmentation methods. The analysis includes the watershed algorithm, active contouring and a cellular automata GrowCut method. One can also find here a description of image pre-processing, Hough transform based pre-segmentation and an automatic nuclei localization mechanism used in our approach. Preliminary experimental results collected on a benchmark database present the quality of the methods in the analyzed issue. The discussion of common errors and possible future problems summarizes the work and points out regions that need further research.

This paper describes an early stage of cytological image recognition and presents a comparision of two hybrid segmentation methods. The analysis includes the Hough transform with conjunction to the watershed algorithm and with conjunction to the active contours techniques. One can also find here a short description of image pre-processing and an automatic nucleuses localization mechanisms used in our approach. Preliminary experimental results collected on a hand-prepared benchmark database are also presented with short discussion of common errors and possible future problems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
